    Default java file processing beginner level

    INFO ABOUT THE PROGRAM
    /*
    dive_data.txt info
    1 3.5 5.5 6.0 7.0 6.5 6.5 5.5 7.5
    2 2.0 8.0 8.5 8.5 9.0 8.0 8.5 8.0
    I already got rid of 1 because it was an int, and the teacher said to remove the int, but I can't get rid of 3.5.
    I want to get rid of 3.5 and store in in a variable. so my math.min is 5.5 instead of 3.5
    I'm having a hard time picking doubles from doubles.
    sorry first time using this website so im kind of disorganized.

    */
    public static double calculateOneScore(String diveLine) { // calculate each
    // diver score
    Scanner console = new Scanner(diveLine); // store diveline in console
    double max = 0.0; // hold the maximum for a line of score
    double min = 10; // hold the minimum for a line of score
    double sum = 0.0; // hold the sum of all score
    double num = 0.0; // num store next double line of file score
    double difficulty = 0.0; // store the difficulty score
    while (console.hasNextInt()) {
    int diverNum = console.nextInt();

    while (console.hasNextDouble()) { // test if the file line as a
    num = console.nextDouble(); // store double in num
    if (num <= 4) { // test the difficulty
    difficulty = num; // store difficulty num
    }
    sum += num; // add sum to num and store in sum
    max = Math.max(max, num); // get the max number
    min = Math.min(min, num); // get minimum
    }
    }
    sum = sum - (max + min);
    sum = sum * difficulty * 0.6;
    return sum;
    }
